Abstract

L'invention concerne un procédé de déclaration d'informations de qualité de canal apériodiques (CQI), selon lequel : un côté de réseau configure un déclenchement de CQI apériodiques sur un terminal, et quand une cellule configurée avec des multipoints coordonnés (CoMP) et une cellule non configurée avec des CoMP coexistent, les informations de configuration de déclenchement de CQI apériodiques de la cellule non configurée avec des CoMP contiennent une valeur de déclenchement de CQI apériodiques configurées sur une base cellulaire; le côté de réseau transmet une requête de déclaration d'informations d'état de canal (CSI) au terminal; et le côté de réseau reçoit la CQI déclarée par le terminal.
